1.3.4 Prevention Hosts of Data Transfer Time-out
† Standard

† Bit Rate
: 12Mbps (Full Speed Device)
† Data Encoding
: NRZI
† Adaptable Connector
: USB Series B
Generally, hosts abandon data transfer to peripherals when a peripheral is in the busy
state for dozens of seconds continuously. To prevent hosts of time-out, the printer
receives data very slowly, several bytes per minute, even if the printer is in busy state.
This slowdown is started when the remaining input buffer becomes several hundreds of
bytes, and the printer is finally in the busy state continuously when the input buffer is
full.
USB and IEEE1284.4 on the parallel interface do not require this function.

In this automatic interface selection mode, the printer is initialized to the idle state
scanning which interface receives data when it is powered on. Then the interface
which receives data first is selected. When the host stops data transfer and the
printer is in the stand-by state for seconds, the printer is returned to the idle state.
As long as the host sends data or the printer interface is in busy state, the selected
interface is let as it is.
† Interface State and Interface Selection
Pin #2
Pin #1
When the parallel interface is not selected, the interface gets into the busy state.
When the printer is initialized or returned to the idle state, the parallel interface
gets into the ready state. Caution that the interrupt signal such as the -INIT signal
on the parallel interface is not effective while that interface is not selected.
1.3.6 IEEE1284.4 Protocol
Pin #3
Pin #4
Figure 1-9. USB pin Assignment
The packet protocol described by IEEE1284.4 standard allows a device to carry on
multiple exchanges or conversations which contain data and/or control information
with another device at the same time across a single point-to-point link. The protocol is
not, however, a device control language. It provides basic transport-level flow control
and multiplexing services. The multiplexed logical channels are independent of each
other and blocking of one has no effect on the others. The protocol operates over
IEEE1284.

when magic strings (1284.4 synchronous commands) are received.

The Printer mechanism for the Stylus PHOTO 810/820 is newly designed. But, the
basic component of the Printer mechanism is almost the same as the previous printer
(Stylus COLOR 480/580). And also, Stylus Photo 820/830 is successor to Stylus Photo
810/820 and is the same as its printer mechanism.
This printer consists of Printhead, Carriage mechanism, Paper loading mechanism,
Paper feeding mechanism, Ink system (Pump mechanism including newly designed
Carriage lock mechanism, Capping mechanism including newly designed Wiper
mechanism).
Clutch mechanism
Like the previous printers (Stylus COLOR 480/580), the Stylus PHOTO 810/820 is
equipped with two stepping motors; one for the Paper loading/feeding mechanism and
the Pump mechanism with the CR lock mechanism, and one for the CR mechanism.
The ASF unit for the Paper loading mechanism uses rear entry front eject system. And,
single LD roller in Holder shaft unit loads a paper to the Printer mechanism.

Revision B
Following explains the basic components for the Printhead.
2.1.2 Printhead
The Printhead uses the same U-CHIPS type as the previous printer (Stylus COLOR
680), and makes it possible to perform multiple shot printing and variable dot printing.
† PZT
PZT is an abbreviation of Piezo Electric Element. Based on the drive waveform
generated on the Main board, the PZT selected by the nozzle selector IC on the
Printhead pushes the top of the ink cavity, which has ink stored, to eject the ink
from each nozzle on the nozzle plate.
The Printhead nozzle configuration is as follows.
† Nozzle layout
† Electric poles for CSIC
Black: 48 nozzles x 1row (nozzle pitch of row: 1/120 inch)
Color: 48 nozzles x 1 row/col (nozzle pitch of row: 1/120 inch)
This electric poles connects the CSIC chip mounted on the ink cartridge. By using
this poles, current ink consumption amount data is red out from the CSIC chip.
And, the latest ink consumption amount data is written into the CSIC chip.
The nozzle layout when viewed from the back surface of the Printhead is shown below.
† Nozzle Plate
The plate with nozzle holes on the Printhead surface is called Nozzle Plate.
† Filter
0.2117(3/360inch)
When the ink cartridge is installed, if any dirt or dust around the cartridge needle is
absorbed into the Printhead, there is a great possibility of causing nozzle clog and
disturbance of ink flow, and alignment failure and dot missing finally. To prevent
this problem, a filter is set under the cartridge needle.
† Ink Cavity
The ink absorbed from the ink cartridge goes through the filter and then is stored
temporarily in this tank called “ink cavity” until PZT is driven.
Figure 2-2. Nozzle layout
CSIC chip
Nozzle selector board
The Printhead has the electric poles to store the ink consumption amount data into the
CSIC chip mounted on the ink cartridge. By storing the ink consumption amount data,
this printer can detect the ink consumption status, such as ink low/end condition.
The basic operating principles of the Printhead, which plays a major role in printing,
are the same as the previous printer (Stylus COLOR 680); on-demand method which
uses PZT (Piezo Electric Element). In order to uniform the ejected ink amount, the
Printhead has its own Head ID (13 digits code for this Printhead for Stylus Photo 810/
820/830) which adjusts PZT voltage drive features.
So, you are required to store the Head ID pasted on the Printhead into the EEPROM by
using the Adjustment program when replacing the Printhead, the Main board, the
Printer mechanism with new one. (Note : there are no resistor arrays to determine the
Head ID on the Main board.) And then, based on the stored Head ID into the
EEPROM, the Main board generates appropriate PZT drive voltage.

2.1.2.1 Printing Process
2.1.2.2 Printing Method
This section explains the process which the Printheads of On-Demand inkjet printers
eject ink from each nozzle.
For printing dot system, the Stylus PHOTO 810/820 has the following two kinds of
printing mode.
1.
2.
Normal state :
When the printing signal is not output from the Main board (C418 Main/Main-B,
C483/C484 Main), or the PZT drive voltage is not applied, the PZT does not
change the shape. Therefore, the PZT does not push the ink cavity. The ink
pressure inside the ink cavity is kept normal. (refer to Figure 2-4 : Normal state)
Ejecting state :
When the print signal is output from Main board (C418 Main/Main-B, C483/C484
Main), the nozzle selector IC located on the Printhead latches the data once by 1byte unit. Based on the drive waveform (common voltage) generated on the Main
board, the PZT selected by the nozzle selector IC pushes the top of the ink cavity.
By this operation, the ink stored in the ink cavity is ejected from nozzles. (refer to
Figure 2-4 : Ejecting state)
Ink path
PZT
„ Multiple shot printing
„ Variable dot printing
The above two printing modes are automatically selected depending on the media and
the resolution setting of the printer driver. The following explains each printing mode.
† Multiple shot printing
This printing mode is developed to improve the print quality on plain paper or
transparencies in low resolution. The multiple shot printing mode uses normal dot,
and the number of dot shot varies from 1 shot to maximum 3 shots depending on
the print data to enable to output sharp image even in a low resolution.
† Variable dot printing
Ink cavity
This printing mode is developed to improve the print quality on exclusive paper.
This mode is basically the same as variable dot printing mode used on other
products; micro dot, middle dot and large dot compose this mode. The printing dot
size varies according to the print data and this mode enables to output even sharper
image on exclusive paper.

2.1.3 Carriage Mechanism
The Carriage mechanism consists of CR motor, Carriage unit (including the Printhead
and CR guide shaft), CR timing belt and CR home position sensor (HP/PE sensor) etc.
Following figure shows you each component for the CR mechanism.
HP/PE sensor
CR motor
HP detection lever
The drive of the CR motor is transmitted to the CR unit via the CR timing belt. And,
the CR home position is detected with the HP/PE sensor. This sensor is available as the
CR home position sensor while the CR motor operates in each sequence. (The function
of this sensor varies depending on the running condition of the motors. It is available as
the PE sensor when the PF motor operates in each sequence.)
When the detection plate molded on the CR unit pushes down the HP detection lever
and the CR home position is detected with HP/PE sensor, HIGH signal is output to the
CPU.

Moreover, like the previous printers (Stylus COLOR 480/580), this printer does not
also have the PG adjustment mechanism. Therefore, the CR guide shaft is assembled
with the defined PG value (1.7 ± 0.2 mm).
For your reference, in case that the CR home position is not detected with the HP/PE
sensor although the CR unit moves correctly, the printer indicates the "Fatal error".
And also, in case that the CR unit cannot move outside the home position and the CR
home position is not detected with the HP/PE sensor, the printer indicates the "Paper
jam error".

Revision B
The drive of the PF motor is transmitted to the LD roller shaft and the PF roller through
gears for the Paper loading/feeding mechanism. The Paper loading mechanism plays a
role in loading a paper from the ASF unit to the PF roller. And also, the Paper feeding
mechanism plays a role in feeding a paper loaded from the ASF unit. The functions of
the Paper loading/feeding mechanism varies depending on the rotational direction of
the PF motor as the table below.

Revision B
For your reference, the top or the end of a paper is usually detected with the HP/PE
sensor. In case that the HP/PE sensor cannot detect the top of a paper in the paper
loading sequence, the printer indicates the "Paper out error". If the HP/PE sensor
cannot detect the end of a paper in the paper feeding sequence, the printer indicates the
"Paper jam error". As for the details, refer to Chapter 3 "Troubleshooting".
2.1.4.1 Paper Loading Mechanism (ASF unit)
The Paper loading mechanism consists of the Change lever in the Pump unit, the
Holder shaft unit (including the Clutch mechanism) and the ASF unit.
The Change lever and the Clutch mechanism play a major role in the Paper loading
mechanism as follows.
1.
ASF home position detection function
The ASF unit on this printer does not have the ASF home position sensor. Instead
of the ASF home position sensor, the Change lever and the Clutch mechanism is
used to detect the ASF home position.
When the Change lever is set on the Clutch mechanism with the counterclockwise
rotation of the PF motor pinion gear, the ASF home position is detected by this
lever for the paper loading operation. In this time, the printer cannot load a paper
from ASF unit because the drive of the PF motor is not transmitted to the LD roller
shaft.
2.
Paper loading function
When the Change lever is released from the Clutch mechanism with the clockwise
rotation of the PF motor pinion gear, the ASF home position detection function is
changed over to the paper loading function. Therefore, the printer can load a paper
from ASF unit because the drive of the PF motor is transmitted to LD roller shaft.
On this printer, the Paper return plate is built in ASF unit instead of the Paper return
lever. The LD pad is stacked on the Paper return plate, and it works with the tension
force of the Torsion spring 29.1 mounted on the ASF frame.
When an arc portion of the LD roller pushes down this plate into the ASF frame during
the paper loading sequence, a paper is loaded from the ASF unit. A cutout portion of
the LD roller releases this lever and this plate returns papers to the stand-by position for
next paper loading operation.
Following figures (refer to Figure 2-8/Figure 2-9) show you the ASF paper loading
sequence and the operation of each mechanism.

While the LD roller rotates
CW direction (right side

a paper is loaded to the PF
roller. In this rotation, the
ASF hopper returns to the
open position and the Paper
return plate is released from
the LD roller. In this time,
this plate returns papers to the
stand-by position in ASF unit
for next paper loading
operation.
Then, when the rolling LD
roller & the Clutch come at
the above “Step1” position,
the Clutch lever is locked
with the Change lever again.
In this time, the drive of the
PF motor is interrupted and
the drive is transmitted only
to the PF roller side for the
paper feeding sequence.

2.1.4.2 Paper Feeding Mechanism
The Paper feeding mechanism consists of PF motor, PF roller, Paper eject roller *1,
Paper end sensor (HP/PE sensor) etc. The Paper feeding mechanism feeds a paper
loaded from ASF unit by using pairs of rollers.
*1
1.
Another pair is the Paper eject roller and the Star wheel which is assembled on the
Front frame. The drive of the PF motor is transmitted to the Star wheel through the
Paper eject roller.
Following figure shows you the transmission path for the PF roller & the Paper guide
roller and the Paper eject roller & the Star wheel.
: Different from the Paper eject roller for the Stylus C60, the metal shaft is used
for this printer to improve the paper feeding accuracy.
The top of a paper is loaded to the PF roller from the ASF unit in the paper loading
sequence. And then, when the PF motor pinion gear rotates CCW direction (left side
view), a paper is fed by the PF roller & the Paper guide roller and the Paper eject roller
& the Star wheel in the printing operation & the paper feed sequence.
One pair is the PF roller and the Paper guide roller which is assembled in the Paper
guide upper/left. The drive of the PF motor is transmitted to the Paper guide roller
through the PF roller.

This is to cover the surface of the Printhead with the cap in
order to prevent the nozzle from increasing viscosity.
Capping mechanism *
Non porous pad in Cap
Due to this, the cap is newly designed as follows.
Ink eject hole
Wiper mechanism
This is to remove the foreign material and unnecessary ink on
the nozzle plate of the Printhead.
Pump mechanism
This is to eject the ink from the ink cartridge, the ink cavity and
the cap to the Waste drain ink pad.
Carriage lock mechanism
This is to lock the CR unit with the Change lever while the CR
unit is at the home position.
*
The Capping mechanism covers the Printhead with the Cap to prevent the nozzle from
increasing viscosity when the printer is in stand-by state or when the printer is off.
Unlike the previous printers (Stylus COLOR 480/580), the Cap unit is newly designed
for this printer as follows.
For Stylus Photo 810/820/830
Ink eject hole
Like the previous printers (Stylus COLOR 480/580), this printer adopts the
valveless cap system. The air valve system used for the previous printer
(Stylus COLOR 740) have two functions by the CR position in the capping
condition as follows.
Porous pad
1) Valve closing condition (CL position)
By closing the air valve, the ink is forcibly absorbed from the ink cartridge or
the ink cavity by the Pump unit and is ejected to the Waste drain ink pad while
the CR unit is in the CL position.
2) Valve opening condition (Ink absorption position)
By opening the Air valve, the negative pressure is decreased and only the ink
inside the Cap is ejected while the CR unit is in the further right side than the
CL position. (the ink is not absorbed from the ink cartridge or the ink cavity.)
For Stylus COLOR 480/580
Figure 2-11. Cap mechanism
Ink absorption position
(valve opening condition)
The Cap unit used for the previous printers (Stylus COLOR 480/580) has the porous
pad to keep the moisture in the Cap *1 and prevent that the air bubbles occur in CL
sequence*2. The following points are modified to get the same effects on new Cap unit
without the porous pad.
But, on the valveless cap system, the above 2) operation is done outside the
capping position. The CR unit moves outside the CR home position and the pump
absorbs the ink inside the Cap.
*1 : The diameter of the ink eject hole is smaller than that of Stylus COLOR 480
/580.
*2 : The cap is modified so that the ink flows with air bubbles to the ink eject hole
in the ink absorption sequence more easily.

Wiper with the Cap unit
The wiping operation is controlled by the CR unit movement. This operation is
usually performed with every CL sequence which is to absorb the ink from the ink
cartridge, the ink cavity by the Pump unit. Following figure shows you the
mechanism for the wiping operation.
Step 2
Step 1
When the CR unit is in the home
position, the hook of the Slider
lock lever is not latched to the
dent of the Cap frame.
In this time, the protrusion of the
Cap slider does not reach the
rightmost position of the Cap
frame.

When the CR unit moves to the left

the Cap unit is pulled back by the
tension force of the Extension spring
0.523.
In this time, the Cap unit is
automatically set to the wiping
position because the hook on the
Slider lock lever is latched to dent of
the Cap frame. And, the wiping
operation is performed according to
the CR unit movement.
The CR unit moves to the wiper
setting position on the rightmost
position of the Cap frame with
keeping the cap covered.
In this time, the hook of the Slider
lock lever is latched to the dent of the

Ink eject operation (usual operation)
The ink is absorbed from the ink cartridge, the ink cavity and is ejected to the
Waste drain ink pad from the cap when the ink tube is pressed by a roller in the
Pump unit.
The PF motor also controls the Pump unit mechanism (including the Change lever) as
well as the Paper loading/feeding mechanism. The drive of the PF motor is always
transmitted to the Pump unit. (And also, its drive is transmitted to the LD roller through
the Clutch mechanism & the Change lever.)

On this printer, the Pump unit mechanism including the Change lever plays a major
role expecting the ink eject operation. And, these operations control depending on the

Carriage lock operation by the Change lever
Unlike the previous printer (Stylus COLOR 680), this printer does not have the
Carriage lock lever with the Wiper.
Instead of the Carriage lock lever, the Change lever is set to the front side of the
printer while the CR unit is in the CR home position.
(As for the detailed mechanism for setting the Change lever, refer to Figure 2-8

2.1.6 Ink Sequence
† Initial ink charge
After the printer is purchased and the power is turned on for the first time, the
printer must perform the initial ink charge to charge the ink inside the ink cavity.
When the initial ink charge is completed properly, the printer releases the flag
inside the EEPROM. The Stylus PHOTO 810/820 takes 80 seconds to complete
the initial ink charge sequence and consumes about 1/10 of the brand-new black
ink cartridge & about 1/8 of the brand-new color ink cartridge. If the power is
turned off during the initial ink charge, the CL1' will be performed at next power
on timing.
† Manual Cleaning
The Stylus PHOTO 810/820 provides four types of manual cleaning to clean air
bubbles, clogged ink with viscosity or foreign substances.
The following manual CL can be performed by the control panel operation, the
printer driver utility and the Adjustment program.

Maximum 0.503 ml of the ink is consumed in the timer cleaning. (0.083ml of
black ink and 0.42ml of color ink are consumed.)

„ Periodical Flashing
This is due to avoid the increment of both ink’s viscosity in the printhead
nozzle during the continuous printing and the specific small amount of the ink
is ejected in the cap based on the periodical flashing timer.
„ Periodical large amount Flashing
This is due to avoid the increment of black ink’s viscosity in the printhead
nozzle during the continuous printing and large amount of the ink is ejected in
the cap based on the periodical large mount flashing timer.
In case that the manual CL and the nozzle check pattern printing is alternately
performed, the CL order is CL1 → CL1' → CL2. (In case that the printer keeps the
power off condition more than the specific period, the CL order is CL2 → CL1 →
CL1' → CL2 → CL1'' → CL2 → CL1 → CL1'.)
Like the previous printers (Stylus COLOR 480/580), CL1 is selected
automatically and performed In case that any printing operation is not performed
between each manual CL. Additionally, if the manual CL is performed with over 5
pages printing cycle, CL1 is always selected and performed.
Additionally, if either black or color I/C is ink low or end condition, any manual
cleaning is prohibited and it is displayed on the LED indicators.
† Timer Cleaning
Like the previous printers (Stylus COLOR 480/580), this printer dose not have
Timer IC and Lithium battery which is used for the backup power source for
Timer IC. So, this printer manages the printer off period or cleaning cycle by using
the following method.
The printer driver sends the timer command to the printer before printing. The
timer command is generated based on the PC's timer and it consists of year, month
date, hour, minute and second. As soon as the printer receives the timer command
from the printer driver, the printer stores its command in address 04 <H> and 05
<H> in the EEPROM. Then, it is compared with the latest CL time which is stored
in address 02 <H> and 03 <H> in the EEPROM. And, In case that the timer

AC voltage input from AC inlet first goes through filter circuit that removes high
frequency components and is then converted to DC voltage via the rectifier circuit and
the smoothing circuit. DC voltage is then lead to the switching circuit and FET Q1
preforms the switching operation. By the switching operation of the primary circuit,
+42VDC is generated and stabilized at the secondary circuit. This +42VDC generated
by the secondary circuit is converted to +5VDC by the chopping regulator IC of the
secondary circuit.

Revision B
Regardless of the state of the power switch (On or OFF), the voltage is always
applied to the primary side of the power supply board from the moment or at the
state that AC-plug is plugged in. At this time, F1 plays a role of preventing
AC100V from coming into the F1.
L1 also prevents high harmonic wave noise generated in the RC circuit filter
which consists of C1 from going out, and eliminates the noise from outside here.
2.
The AC is full-wave rectified by the diode bridge DB1, and converted to
AC in voltage by the smoothing electrolytic capacitor C11.
3.
The pressured up direct current turns Q1 on through the starting resistor R31 and
starts the primary side of the circuit.
4.
5.

When the primary side is On, the energy (current) led by the electromagnetic
induction through the trans (T1) does not flow to the secondary side since the
diode (D51) on the secondary side is installed in the opposite direction.
When the energy which is charged in the trans is reaching the saturated state, the
voltage which makes Q1 on becomes weak gradually. At the point that this voltage
drops at the certain voltage, C13 absorbs the current in the opposite direction and
Q1 is quickly shut off by the resulting sharp drop.
6.
When the primary side is turned off, the energy charged in the T1 is opened
according to the diode (D51) direction which is installed on the secondary side.
Basically, 42 V DC is output by these circuit operations and the number of T1
spiral coil.
7.
+5VDC is generated by pressured down this +42VDC as power supply. IC51
pressures down the +42VDC and generates precise +5VDC by chopping off the
output, forming the standard santooth wave form by the outer RC integration
circuit.
† +42Vline over voltage protection circuit :
The output voltage line is monitored by ZD52 and ZD87. If the output voltage
level of +42VDC line exceeds +48V, this circuit stops the operation of the
switching FET Q1 via PC1,Q82 and Q83, and prevents high voltage from being
applied to the secondary side.
† +42VDC line drop limitation circuit :
PC1 drives with +36V and ZD90 is monitoring the voltage supplied to PC1. If the
supplied voltage level exceeds 37V, this circuit shuts down the +42V line
temporarily and prevents the over voltage from being applied to the PC1.
† +42Vline over current protection circuit :
The output current level is monitored by the F51. When the abnormal current is
detected by F51, F51 blows and cuts off the +42V line output to the Main board.
† +5V line constant voltage control circuit/+5V line over current protection circuit :
The output voltage level of the +5VDC line is monitored by the regulator IC51. If
abnormal voltage is detected, the information is fed back to the internal
comparator.
† +5V line over voltage protection circuit :
The output voltage level of the +5VDC line is monitored by ZD53.
If the output voltage level of +5DC line exceeds +7V, this circuit stops the
operation of the switching FET Q1 via PC1,Q82 and Q83, and prevents high
voltage from being applied to the secondary side.
The C417 PSB/PSE board has the various control circuits to stop voltage output if a
malfunction occurs on the power supply board or the main board or while the printer
mechanism is on duty. Following explains each control and protection circuit.
† +42V line constant voltage control circuit :
The output voltage level of the +42V line is monitored by R92, R93, Q91 and
ZD51. When +42V line reaches about +42.8V, PC1 starts the operation via Q91.
Consequently, FET Q1 switching operation is controlled by this circuit to stabilize
the +42V line.

The common driver (IC19) generates a basic drive waveform according to the output
signals from CPU (IC1). The basic drive waveform is amplified by the transistors Q2
and Q3 (the amplified one is called drive waveform.) and then transferred to the nozzle
selector IC on the printhead driver board. Print data is converted to serial data by the
CPU and then sent to the nozzle selector IC on the printhead driver board. Based on the
serial data, the nozzle selector IC determines the nozzles to be actuated. The selected
nozzles are driven by the drive waveforms amplified by the transistor Q2 and Q3. See
refer to Figure 2-19 for the printhead driver circuit block diagram.
† Head common driver circuit
The basic drive waveform is generated in the common driver (IC19) based on the
following 12 signal lines output from the CPU (IC1); A0-A4, CLK1, CLK2,
FLOOR, RST, DATA, DCLK, and E.
By the DATA signal output from the CPU, the original data for the basic drive
waveform is written in the memory in the common driver (IC19). The addresses
for the written data are determined by A0-A4 signals. Then, the necessary data is
selected from the address and appropriate basic drive waveform is generated.
Generated basic drive waveform is transferred to nozzle selector IC on the
printhead driver board through the transistor Q2 and Q3 and applied to the nozzle
PZT specified by nozzle selector IC.

determines the phase mode.
CPU (IC1) transmits LB1946 micro step drive form and the current value date on each
phase to motor driver IC (IC11) from port 142. Based on this signal, motor driver IC
determines the phase mode.
Motor driver IC generates motor driver waveform based on these input signals and
controls the motor. And also, motor driver IC monitors to prevent the fluctuations in

The printhead driver circuit consists of the following two components:
„ Head common driver circuit (Common driver IC10 & Wave amplifier
transistor Q1, Q2)
+42V
Common
Driver(IC10)
19
„ Nozzle selector IC on the printhead driver.
The common driver (IC10) generates a basic drive waveform according to the output
signals from CPU (IC8). The basic drive waveform is amplified by the transistors Q1
and Q2 (the amplified one is called drive waveform.) and then transferred to the nozzle
selector IC on the printhead driver board. Print data is converted to serial data by the
CPU and then sent to the nozzle selector IC on the printhead driver board. Based on the
serial data, the nozzle selector IC determines the nozzles to be actuated. The selected
nozzles are driven by the drive waveforms amplified by the transistor Q1 and Q2. See
refer to Figure 2-26 for the printhead driver circuit block diagram.
† Head common driver circuit
The basic drive waveform is generated in the common driver (IC10) based on the
following 12 signal lines output from the CPU(IC8); A0-A4, CLK1, CLK2,
FLOOR, RST, DATA, DCLK, and E.
By the DATA signal output from the CPU, the original data for the basic drive
waveform is written in the memory in the common driver (IC10). The addresses
for the written data are determined by A0-A4 signals. Then, the necessary data is
selected from the address and appropriate basic drive waveform is generated.
Generated basic drive waveform is transferred to nozzle selector IC on the
printhead driver board through the transistor Q1 and Q2 and applied to the nozzle
PZT specified by nozzle selector IC.
† Nozzle selector circuit
Printing data is allocated to the six rows (the number of the head nozzle rows) and
converted into serial data by the CPU (IC8). Then the converted data is transferred
to the nozzle selector IC through the six signals lines (HS01 to HS06). Data
transmission from the CPU to the nozzle selector synchronizes with the LAT
signal and SCK clock signal. Based on the transmitted data, appropriate nozzle is
selected and the PZTs of the selected nozzle are driven by the drive waveform
output from the head common driver.

2.2.3.3 PF/CR Motor Driver Circuit
The motor driver IC (IC6) on the Main board drives PF/CR motor. This product uses 4phase 96-poles HP type stepping motor (PF motor) and 4-phase 200-poles PM type
stepping motor. And these motors perform constant current bi-polar drive.
CPU (IC8) transmits A6615 micro step drive form and the current value data on each
phase to motor driver IC (IC6) from port 89/92. Based on this signal, motor driver IC
determines the phase mode.
Motor driver IC generates motor driver waveform based on these input signals and
controls the motor. And also, motor driver IC monitors to prevent the fluctuations in
the actual current value to motor driver IC. If motor driver IC detects the fluctuations in
the actual current value, it amends the current value internally.
In case that the printer dose not receive any data for 30seconds, CPU set the motor
drive current to 0 [A] and the motor drive is turned off to save the power consumption.
* Unlike the Stylus C50/C60, regulator IC which generates +5VDC is not on the
C482 PSH board for the Stylus C61/C62. Instead of the regulator IC, +5VDC is
generated on this motor driver IC.

3.3 Unit Level Troubleshooting
You can identify the troubles by using the checklist in this section after confirming the
LED indication on the printer. If you connect the printer to your PC and see an error
message on the STM3, you can short the total repair time. And, when you find out the
defective parts, replace them by referring the Chapter 4 “Disassembling”. Following
tables describe the error condition (LED and STM3), possible cause and check point.
The following is the example of how to use the table.
When the CR unit is out of the home position at the power on timing, the fatal error
may be caused by the failure of the CR motor. Moreover, there are 3 possible causes on
the CR motor failure.
[Note]
When the individual part of the Paper eject roller, PF motor and the Ink system unit is
defective, replace the Printer mechanism to new one basically.
However, if the individual part is replaced to new one in the urgent case, disassembly/
reassemble it carefully by referring to Chapter 4.

SP810/820 and SP820/830
2) Main board
The size/connector position of the main board is changed as below.
The Stylus Photo 820/830 is successor to the Stylus Photo 810/820, and is the same as
its printer mechanism basically. However, some modificaitons has been taken on
Stylus Photo 820/830 since the first mass production. Followings show you the
difference on the printer mechanism between Stylus Photo 810/820 and Stylus Photo
820/830.
1) SW botton
The shape/material of the SW button is changed as below.
- Stylus Photo 810/820 : It is assembled to the M/B mounting plate by the two
hooks of the SW button.
- Stylus Photo 810/820 : It is assembled to the Upper housing by the two hooks of
the SW button.

† When disconnect/connect the harness/connector of the CR
motor/PF motor/Head FFC, be careful not to hurt your hand
with the protrusion of the main board shiel plate. (Red circle
portion in Fig. 4-2.)
3) CR motor/PF motor*/Head FFC
Due to the above 2), the length of each harness/connector is longer than current one.
* The specification of the PF motor is newly changed for the Stylus Photo 820/830.
4) P/S baord
a. The type of the AC cable is changed to AC inlet on the Stylus Photo 820/830.
b. The Stylus Photo 810/820 has the Power supply radiator on the P/S board.
However, the Stylus Photo 820/830 does not have it. (Screw position on the P/S
board is the same as the Stylus Photo 810/820.)

: Bk - T026, Col - T027
† If other I/C is installed on Stylus Photo 810/820/830, the printer
detects ink end error.
6) Paper eject roller shaft
The Stylus Photo 820/830 has two kinds of the paper eject roller shaft. One is
metaric roller shaft, and another is plastic roller shaft. (The Stylus Photo 810/820 has
metaric one only.) The interchangeability has not kept completely between the lower
housing and the paper eject roller. The product with the plastic roller is used the
exclusive lower housing. (This lower housing can be used for the Stylus Photo 810
/820.)
Since some ink leakage mode has already found on Stylus C60, Stylus Photo 810/820
(one is caused by ink tube miss-setti ng, and the other is caused by ink collected in the
Cap frame during transportation), we would like you to perform the following action in
your repair/refurbishement.
1) Ink tube miss-setting
a. Place the ink tube on the Lower housing correctly.
b. Confirm the condition of the tip of the ink tube.
c. Put the "Porous Pad, Ink Tube Stopper" on the Lower housing correctly.
* Refer to the "Waste drain ink pad removal".
2) Ink collected in the Cap frame
When the printer wipes off the surface of the print head, waped ink may possibly
collect in the Cap frame. In this time, in case that the printer is transported with
incorrect way, ink drops to the Upper houing directly via the Cap frame. Then, ink
may leaks outside of the printer.
a. Check the ink collection condition in the Cap frame.
b. Wipe up the ink by using the cotton bar and so on, if you can see the ink.

should be followed in the urgent case. In this time, the disassembly procedure is different depending on the removed unit.
* Ink system unit : ASF unit, CR unit, PSB/PSE unit, Holder shaft unit, Lower housing
* PF roller/PF motor : ASF unit, CR unit, PSB/PSE unit, Lower housing
*3) Unlike the paper eject roller shaft for the Stylus C50/C60/C61/C62, there is not two hooks on the paper eject roller shaft for the Stylus Photo 810/
820830. So, you can remove it from the Printer mechanism. However, you cannot replace it to new one because its roller shaft is not established
for service part.

5.1 Overview
In this printer, it is necessary to perform appropriate adjustment in order to maintain
consistent printing function and quality, eliminate differences of each printer
mechanism’s characteristics.Therefore, in case that the combination between the
printer mechanism and the main board changes or the Printhead is replaced during the
repair service, you must input the correct adjustment value into the EEPROM on the
Main board by using the Adjustment program.
This section describes the procedure for adjustments required when the printer is
disassembled and assembled for repair or service.

MAINTENANCE
EPSON Stylus PHOTO 810/820/830
Revision B
6.1 Overview
6.1.2 Service Maintenance
If any abnormal print (dot missing, white line, etc.) has occurred or the printer indicates
the "Maintenance request error" (This error is displayed as "Maintenance call error" in
the STM3), take the following actions to clear the error.
This section provides information to maintain the printer in its optimum condition.
6.1.1 Cleaning
† Printhead cleaning
This printer has no mechanical components which require regular cleaning except the
Printhead. Therefore, when returning the printer to the user, check the following parts
and perform appropriate cleaning if stain is noticeable.
C A U T IO N
„ Never use chemical solvents, such as thinner, benzine, and
acetone to clean the exterior parts of the printer like the Housing.
These chemicals may deform or deteriorate the components of the
printer.
„ Be careful not to damage any components when you clean inside
the printer.
„ Do not scratch the coated surface of the PF roller. Use soft brush
to wipe off any dusts. Use a soft cloth moistened with alcohol to
remove the ink stain.
„ Do not use cleaning sheet included in the media for normal usage.
It may damage the coated surface of PF roller.
If the adhesive surface of the cleaning sheet is set to the LD roller
shaft side and used to clean the LD roller surface, it is no
problem.
When dot missing or banding phenomenon has occurred, you need to perform the
printhead cleaning operation*1 by using the printhead cleaning function. This
function can be performed by the control panel operation, the printer driver utility
and the Adjustment program.
In case that the cleaning sequence is performed by the control panel operation,
confirm that the printer is in stand-by state (the Power LED is lighting), and hold
down the Error reset button on the control panel for more than 3 seconds. Then,
the printer starts the cleaning sequence (the Power LED blinks during this
sequence).
In case that you select and perform the manual cleaning by the printer driver
utility, the most appropriate cleaning mode is selected. The following is the
process to perform the printhead cleaning from the printer driver utility.
As for the operation of the Adjustment program, refer to Chapter 5 Adjustment.
*1: The Stylus PHOTO 810/820/830 has four modes for manual cleaning, and
even during printing, the appropriate cleaning mode is automatically selected
and performed according to various conditions. Therefore the ink consumption
amount for manual cleaning varies depending on each mode (Refer to
Chapter 2).
† Exterior parts
Use a clean soft cloth moistened with water, and wipe off any dirt. If the exterior
parts are stained by the ink, use a cloth moistened with neutral detergent to wipe it
off.
† Inside the printer
Use a vacuum cleaner to remove any paper dust.
† LD Roller
When paper loading function does not operate because friction of the LD roller is
lowered by any paper dust, set the adhesive side up of the cleaning sheet (included
in the media) to remove any paper dust. Repeat loading the cleaning sheet several
times.
Maintenance
Overview
130
EPSON Stylus PHOTO 810/820/830
1.
Revision B
Select the “EPSON Status Monitor 3” in the printer driver utility, and make sure
that the printer is in stand-by state by using the Status monitor 3. If the printer is in
stand-by state, the following figure is indicated on the monitor.
† Maintenance request error (Maintenance call error)
Ink is used for the printhead cleaning operation as well as the printing operation.
When the ink is used for the printhead cleaning operation, the ink is drained to the
Waste drain ink pad and the amount of the waste ink is stored as the waste ink
counter into the EEPROM on the Main board. Due to this, when the waste ink
counter has reached the limit (Waste ink counter = Protection counter A = 32915
points) of the absorbing capability of the Waste drain ink pad, the Maintenance
call error is indicated on Status monitor 3 as following figure.
Figure 6-1. Status monitor 3 indication
2.
Select the “Head Cleaning” in the printer driver utility, and perform the printhead
cleaning. After performing the printhead cleaning operation, print a nozzle check
pattern by selecting the “Nozzle Check“. If you repeat the printhead cleaning
operation without selecting the “Nozzle Check”, CL1, the weakest cleaning, will
be repeated.
Figure 6-3. Maintenance error indication in STM3
In this case, replace to new Waste drain ink pad and clear the waste ink counter stored
into the EEPROM. The waste ink counter can be reset only from the Adjustment
program because this printer dose not have the waste ink counter reset function by the
control panel SW. As for the procedure, refer to Chapter 5 Adjustment.
In your repair activity, check the waste ink counter along with the firmware version,
Main board checker program version and nozzle check pattern on the nozzle check
pattern printing. If the waste ink counter is closed to its limit, recommend that the
Waste drain ink pad will be replaced with new one. This is because the "Maintenance
request error" will may occur after returning the repaired product to the customer.
